How do you use Kustomize with an ArgoCD Application?

Intermediate

Answer

Point the source path at a directory containing a kustomization.yaml; ArgoCD runs `kustomize build` to render manifests. You can set images, name prefixes/suffixes, and common labels via the kustomize section, and structure base + overlays per environment so each Application references the right overlay.
source:
  path: overlays/production
  kustomize:
    images:
      - myapp=myrepo/myapp:v2.0
    namePrefix: prod-
Real-world example The production Application points at overlays/production, which patches the shared base with prod-specific replicas and image tags.
